Reihe: Analog Circuits and Signal Processing

This book describes techniques for designing complex, discrete-time Delta/Sigma ADCs with signal-transfer functions that significantly filter interfering signals. The book provides an understanding of theory, issues, and implementation of discrete complex Delta/Sigma ADCs. The concepts developed in each chapter are further explained by applying them to a target application of Delta/Sigma ADCs in DTV receivers.

Focuses on complex Delta/Sigma ADCs and techniques for their implementation;
Describes techniques to alleviate problems in implementation, such as image rejection deterioration due to mismatches;
Discusses advantages of filtering STFs and describes an architecture for their implementation;
Includes Matlab, Simulink, and Mathematica code used in design and behavioral simulations for design and implementation of complex Delta/Sigma ADCs.
